Specification of Letters Patent.

Application filed. February 12, 1920. Serial No. 358,218.

the borough of- Manhattan, city of New,

York, in the county of New York and State of New York, have invented certain new and useful Improvements in Brushes, of which the following is a specification.

This invention relates to brushes, with the ordinary wooden back or body portion having fibrous material or the usual bristles on one side, and an abrasive material'like pumice stone on the opposite side of the back. The object of the invention is to introduce a pliable material between the upper surface f the back of the brush and the abrasive material, the said pliable material yielding in case of the warping of the back or body portion of the brush. By means of the introduction of the pliable material the abrasive material, usually pumice stone, is prevented from breaking in case of any warping or distortion of the back or bocy portion of the brush.

In the present invention a layer of cork or a plurality of disks of cork or like material are interposed between the back of the' brush and a piece of pumice stone. The three elements are cemented together by means of a waterproof cement. This produces a brush with a pumice stone on its back that is not detrimentally affected by either hot or cold water.

The present application is an exemplification of the invention which may be varied in various ways within the spirit of the claims.

Figure 1 represents a side elevation with a partial vertical axial section of one form of the improved brush; Fig. 2 showsatop plan View of Fig. 1; Fig. 3 is a side elevation with apartial vertical axial section of another form of the brush and Fig. 4 represents a top plan view of Fig. 3;

Referring to Figs. 1 and 2, a brush is indicated with the usual back or body portion 10, having the bristles 11 extending from the normal lower face of the said back 10.

To the upper face of the back of the brush 10 are cemented by means of waterproof February, A. 1920.

cement the cork disks 12. A'pumice stone 14 is cemented to the top faces of the disks 12 by means'of waterproof cement.

Referring to Figs. 3 and 4 there are indicated the back or body portion 10 and the bristles 11. A layer of cork 16 is cemented to the top face of the back or body portion 10 of the brush and to the top face of said layer is cemented the pumice stone 14 by means of waterproof cement. In both forms of the invention the pumice stone is securely held in place and should the back 10 warp in any direction, the yielding property of the cork disks 12 or the layer of cork 16 prevents the brittle pumice stone 14 from breaking.

To make the improved brush, the operatorsecures to the top face of back 10 having the brustles 11, the layer of cork 16 or a plurality of cork disks 12. Then the pumice stone 14 is located upon the layer of will 16 or the disks of cork 12. Waterproof cement is at the same time interposed between the cork and the back of the brush and the pumice stone. 7

Having described my invention what I desire to secure by Letters Patent and. claim is 1'. The combination with a brush having a wooden back, of an abrasive block yields ingly carried thereby.

2. In a brush the combination of a body portion, bristles extending from one side of the body portion, pumice stone on the other side of said body portion, cork interposed between the body portion and the Patented Sept. 7, 1920.

pumice stone and cement binding the body I portion, cork and pumice stone together.

3. In a brush the combination of 'a body portion, a yielding element on the back of the body portion and an abrasive block bearing on the yielding element.

4. In a brush the combination of a body portion, a plurality of yielding disks on the back of the body portion and an abrasive block bearing on said disks.

Signed at the borough of Manhattan, city of New York, in the county of New York and-State of New York, this 6th day of STUART SPEIRS.
